An apparatus is provided and includes an inlet, including a peripheral wall formed to define a pathway along which gaseous, fluidic and particulate matter flow and two or more nets sequentially disposed in the pathway, the two or more nets being suspended on the peripheral wall with substantially no clearance between each of the two or more nets and the peripheral wall and held sufficiently loosely to permit relative movement of each of the two or more nets such that an effective pore size of the two or more nets is variable over time to encourage fluidic condensation at the two or more nets and to permit a relatively substantial portion of the gaseous and particulate matter to continue to flow.
